Following the events above Yavin, the Rebel Alliance LieutenantCaluan Ematt was ambushed by Imperial forces on the Inner Rim world of Taanab but managed to flee to the planet Cyrkon in Hutt Space.[17] The Empire also annexed the planet Riosa and conscripted the planet's population and resources into building both the first and second Death Stars. Riosa's manpower and resources were plundered to fuel the Imperial war machine, causing great hardship and impoverishment to the planet. The future New Republic SenatorRansolm Casterfo grew up during Imperial rule and lost his parents to hard labor. As a result, Casterfo developed a hatred of Darth Vader.[4]

After FleetAdmiral Rax seized control of the Imperial remnant fleets, he ordered his armadas to assemble above the planet Jakku for a showdown with the New Republic, the successor government to the Rebel Alliance.[9] The ensuing Battle of Jakku was a cataclysmic battle which ended the Galactic Civil War in favor of the New Republic. As a result of the fighting, Jakku's surface was littered with the wreckage of countless starships from both sides. Jakku became home to scavengers who sifted through the wreckage for objects to sell.[2] A month after the Battle of Jakku, Imperial remnant forces were confined by the New Republic to parts of the Inner Rim and the Core Worlds as a prelude to the Galactic Concordance.[16]

By 28 ABY, the Inner Rim planets Riosa and Bastatha had joined the New Republic. Their senators including Casterfo were aligned with the Centrists, a political faction in the Galactic Senate who favored greater centralization and a stronger military. Riosa remained a backwater manufacturing center which had still not fully recovered from Imperial rule. Bastatha was a barren desert world that hosted an Amaxine warriors' camp led by the former Imperial Arliz Hadrassian, who was an agent of the First Order, a remnant of the Old Empire.[4]

Following the death of Birren's reigning Supreme governor Mellowyn, the Populist Senator Leia Organa and her son Ben Solo were designated as the heirs to the supreme governorship. Since Leia and Ben were not interested in assuming that office, Organa agreed to support LadyCarise Sindian's bid to inherit the supreme governorship of Birren. However, Sindian was an undercover First Order agent who used her position to discover information about Organa's true parentage as the daughter of Darth Vader. The ensuing scandal destroyed Organa's political career. In retaliation, Organa convinced the Elder Houses to strip Sindian of all her royal titles.[4]
